Connector boards turn a microcontroller’s native signals into practical interfaces for the rest of a system. Breakout boards expose pins for audio jacks, video ports, USB hubs or serial standards such as RS‑232, letting a prototype move from a breadboard to a real‑world device with minimal wiring. Bus adapters and extenders convert I²C‑style connectors into plug‑and‑play formats, increase the number of available ports, or boost signal range for longer cables, while maintaining the timing and voltage requirements of the host. Their compact, surface‑mount designs and built‑in level‑shifting circuitry provide reliable, repeatable connections that integrate easily into hobby or professional projects ranging from sensor rigs to display controllers and embedded communication hubs.
